SOLIDS CONTROL POEM

I am in the business of solids control equipment and solids control system.

Although equipment is cold, I’d like to bring life to the equipment as I am a vividly woman with a lot of hobbies, music, dance, swimming, tennis, etc.

Sometimes, I share some poem with foreigner, except for trading, I’d like to share Chinese culture with customers in different industries, oil and gas drilling, horizontal directional drilling, TBM, CBM drilling, etc.

POEM NAME:
The Charms of Niannu

POET: Shushi (Year 1083, when he was in 46, he wrote this poet. And he is the famous poet in our history for his bold and his heroic style)

*****
The waves of the mighty river flowing eastward
Have swept away the brilliant figures of a thousand generations.
West of the old fortress,
So people say, is Lord Zhou’s Red Cliff in the time of the Three Kingdoms.
The tumbling rocks thrust into the air;
The roaring surges dash upon the shore,
Rolling into a thousand drifts of snow.
The River and the mountains make a vivid picture—
What a host of heroes once were!

And I recall the young Lord then,
Newly married to the fair younger Qiao,
His valorous features shown forth;
With a feather fan and a silken cap
Amid talking and laughing he put his enemy’s ships to ashes and smoke.
While my thoughts wander in the country of old,
Romantic persons might smile at my early grey hair.
Ah, life is but like a dream;
With a cup of wine, let me yet pour a libation to the moon on the river.

Vertical cutting dryer
What parts frame a vertical cutting dryer? it’s a flow-in pipe and overflow pipe, symmetrically structured for each ends to produce installation with convenience. With the overflow pipe for following stage, mud desilter ends up in the opposite lubricant tank by associate degree 8″ rubber hose. The suspension exit of the sand pump and also the flow-in pipe of mud desander area unit connected with a rubber hose. it’s necessary to envision the angle. underneath the perfect operating condition, the running angle at very cheap ought to be 20°~30°. to boot, drilling fluids desander ought to be cleansed fully, and dirt desilters in addition. it’s vital to try to to thus once the suspension has serious consistency to be processed.

Brightway Vertical cutting dryer is intended per principle of grain settlement and also the lubricant rotationally enters on the inner wall of the hydrocyclone through pressure and rate generated by a sand pump to atiny low extent. The thicker granules will go down in spiral mode on the inner wall of hydrocyclones underneath force and gravity in order that lubricator discharged from very cheap exit. The discharged granules area unit separated on the close-mesh sieve, with the remainder of the medium growing in a very spiral mode through the hydrocyclones to enter into the third separating plant from the overflow mouth for any clearance. The drilling fluids solids management looks to be straightforward, truly it’s skilled and sophisticated.

vacuum degasser

Vacuum degasser is our factory based on the comprehensive domestic and foreign various degasser developed a new special equipment for processing gas immersion fluid. Which is applicable to all types of mud purification system supporting, for the viscosity performance and recovery the proportion of mud, stable slurry, reduce drilling cost, has a very important role. At the same time, and also can serve as an mud agitator with high power.

Vacuum Degasser

Vacuum Degasser

The degasser is an vacuum degasser which is the use the suction of vacuum pump,produce a negative pressure zone in the vacuum tank, mud under atmosphere, through a hollow shaft suction tube enter into the rotor,and then through the hollow shaft around the window, a spray thrown to the tank wall, due to the collision and separation wheel effects,which make the drilling liquid separated into a thin layer, the bubble immersed in the mud is break up, gas discharged through suction of the vacuum pump and the mud gas separator separation effects, gas from the separator exhaust pipe discharge into safe areas, mud is discharged from the impeller tank. Because of the opening of the main motor, rotating impeller motor connected with mud in a high-speed condition. Therefore,mud only can from the suction tube enter into the tank, and not be sucked from the drainage tube

Vacuum degasser

Brightway Vacuum degasser, one in all the common solids management instrumentation, is wide employed in well drilling. Then, however it works?

The higher finish of liquid level management device gas guide pipe within the physical phenomenon path between the air chamber of vacuum degasser, the air guide pipe at the lower finish of the float moves upwards below the action of the plunger, the float isn’t influenced by the external pressure distinction, once the liquid level rises, float beside the air guide pipe is straightforward to rise to the peak of the corresponding, the action method is following:

Guide air seat put in within the deaerator head, higher guide air seat cavity through the vacuum waterproofing plug and gas guide seat is axially organized pores with vacuum tank consistent.

When the liquid level within the vacuum degasser is accumulated to the liquid level float up, float through the link pin drives the guide tube to move; once the guide hole pipe through the air guide seat is organized on the radial direction of the opening and also the atmosphere at identical time, decline within the thermionic valve, the liquid drop, liquid level float to guide quiesce, guide tube and outdoors atmosphere between guide gas interface is reduced or closed, to take care of the vacuum degree within the vacuum degasser.

Due to the adoption of thermionic valve higher cavity and vacuum degasser to stay the pressure balance is consistent, will create the conducting pipe interface to extend, this will increase the sensitivity of the liquid level management device.

At identical time, vacuum degree to maximise the degasser in vacuum degasser permission, in up the the initial impact, additionally to the safe operation of the solids system is bonded.

centrifugal pump

What is solids management centrifugal pump detail?
In solids management mud system, there have centrifugal pumps for hydrocyclones. The mud transfer pump for charging centrifuge, the lubricating substance compounding pump for configuration, and/or the cutting pump for shredding lubricating substance, the trip pump, etc. we have a tendency to can also say, there’s horizontal pump, vertical pump, screw pump, etc.

Different equipments request completely different pumps as power resource or mud provides. Meanwhile, {different|totally completely different|completely different} solids system configuration can have different pumps position, design, or types.
Detail pump in field solids management
For solids management equipments, the separated hydrocyclone separators or mud cleaner we have a tendency to should match pump as mud feeding pump. The centirfugal pump transfer lubricating substance to the cyclones body of water line for resultant method.
Usually, these pumps area unit horizontal one. They’ll be mounted on mud tanks ends or below the slant plate of shaker tank. ?When we have a tendency to set pumps below shaker tank can save abundant area. However, then it’ll be inconvenient once we repair or examine pumps.
But generally in solids system there’ll be vertical pump or submersible suspension pump rather than horizontal pumps.
We know in solids system, the lubricating substance appears blood to our physique. where as centrifugal pump are the transfer tools. They pump lubricating substance from here there between completely different lubricating substance tanks or compartments.Let’s see, once mud cleaner or hydrocyclone desilter what pumps there? affirmative, the fourth solids management equipment-Decanter centrifuge. For bottle centrifuge, we’d like pump transfer lubricating substance from desilter compartment to centrifuge input.

Brightway vacuum degasser

Only if the harmful gas is removed from well drilling, a drilling operation can go on. Therefore, degasser plays an important role in drilling. Vacuum degasser is the necessary to learn something about this part of solids control system.

Vacuum degasser is an effective technique to ensures the safety of welling drilling, its reliability, safety and efficient operation will be an important guarantee for the safe drilling.
